During the second-half of the last century countries were placed in one of two mutually exclusive camps: north or south, east or west, advanced or emerging, developed or developing. Simple though this categorization of countries had been, it reflected prevailing realities. In 1970, for instance, the global distribution of per capita income showed a clear divide between richer and poorer countries (See Figures 1 and 2). These between-country differences were equally applicable to other development conditions, notably health and education. However, as Hans Rosling emphasized during his last presentation at the World Bank, for the 21st century this binary distinction between countries is outdated. Boundaries between developed and developing regions are less clear today because of the extraordinary social and economic progress achieved in the large majority countries. Global economic activity is less geographically concentrated and increasingly dispersed across production networks that connect metropolitan areas around the world.
